The Capitol Police Board is a group of three members who maintain jurisdiction over the United States Capitol Police. The three members of this board are the Architect of the Capitol Stephen T. Ayers, the Sergeant at Arms of the United States Senate Frank J. Larkin, and the Sergeant at Arms of the United States House of Representatives Paul D. Irving. The Chief of the Capitol Police also serves as a member but in an ex officio status.
These same three individuals also made up the United States Capitol Guide Board which has jurisdiction over the United States Capitol Guide Service until the board and service were abolished in 2008. The position of Board Chairman is alternated between the House of Representatives Sergeant at Arms, who serves as the chairman during even years, and the Senate Sergeant at Arms, who serves during each odd year.
